struction, not liable easily to get out of or-v der, and arranged foruse as a stop cock in case it is desired to4 completely shut oil thesupply of water from the iushing tank or other similar device.

For the purpose mentioned use is made of a valve body provided with avalve seat, a

valve disk for engagement with the said seat and having its stem mountedto slide in the said valve body, and a lever having a slot engaged bythe pivot pin of the lever and by a pin on the said valve stem, the saidpivot pin being arranged in the wall of the valve body. Uselis 'alsomade 'of a screw screwing in the valve body'for forming a stop for thevalvedisk and for moving the stem into closed position on the valve seatandl locking it in-'this closed p0- 4 sition.`

A practical embodiment of the invention is representedin theaccompanying drawings forming a part of this specification in whichsimilar characters of reference indicate corresponding parts in all theviews. c

Figure 1 is a side elevationv of the valve arranged as aoat-controlledsupply valve for the top of a flushing tank, the latter being shown insection; Fig. 2 isan enlarged sectional side elevation of the same; Fig.3 is a sectional plan view of part of the stem on the line 3-3 of Fig.2; Fig. 4 is a cross section of the same on the line 4 4 of Fig. 3;,Fig.5 is a similar view of the same on the line 5-5 of Fig. 2; and Fig. 6 isa perspective view of the valve disk and its stem.

lThe valve body A is provided with a flange B for fastening the valvebody to a flushing tank C or other device, and on the said valve body isscrewed or otherwise secured an inlet D connected with a pipe E leadingto a source of water supply. The

,bottoni of the valve body A is provided with an outlet F in which issecured a pipe G extending down into the tank .C tosuppl the latter withwater. A valve seat D is arranged on the inner end of the inlet D, andthe said valve seat D is adapted to be engaged by a valve disk Hfastened by a screw or other fastening device I to the inner end of avalve stem J mounted to slide in abearing K forming part of the yvalvebody A- and arranged in axial aline- `ment with the valve seat D.

end JJ of the valve stem J is forked, and

The outer the lforked members J 2, J 3 are cut out on the under side andare provided with a transverse pin L extending through a slot Ny formedin a oat lever N pivoted on a pivot pin O removably secured in the wallof the bearing K vand extending through the'slot N', as plainly shown inFig. 2. By providing the lforked members J2, J3 with a cut-out portionon the under side sufficient room 'is had for the Vpassage of the pivotpin O .to allow free forward and backward movement of the valve stem Jand to permit of securing the pivot pin O in the side walls ofthebearing Kat a lpoint intermediate theI axis ofthebearing and theouter surface thereof whereby thesaid'pivot pin O is located vin closeproximity to the pin L to provide a short leverage at the slotted end ofthe iioat lever N, thus rendering the latter exceedingly' forcible inpushing the valve disk H to its vSeaton swinging the float lever N in anupward direction. The lever N extends through aslot K in the bottom ofthe bearing K, andthe lever N is provided with the usual socket N2engaged by the float rod N3 fastened in place in the socket by a setscrew N4.

When the valve disk H is in openvposition, then water flows into thetank C to fill the same and in doing so `the fioat on thev end of thefloat rod N rises thus imparting a' swinging motion to the lioat lever Nwhich by its connection withthe pin L moves the stem'J and consequentlythe valve disk H inwardly until the valve disk H finally engages the,seat D and closes the, same thus hutting off the supply of water to thetank j. When the water level in the tank C falls the-n a downwardswinging motionv is given to the float lever whereby the valve stem Jand the valve disk H are moved in an outward direction and the valvedisk uncovers the valve seat D to allow water to pass through the valveinto the tank C, as before explained. The .outer end of the bearing K sothat when the disk H is moved intok open position by the action of thefloat lever then the opening movement of the disk H and that of the stemJ is limited by the screw Q.

By screwing the screw further in or further -out the valve disk H isallowed to open more or less as desired. When it is desired to shutl othe supply of water to the tank C then the operator screws the screw Qinward thus moving the stem J and consequently the valve disk H inwarduntil the valve disk H is firmly seated on the seat D, and A,when thistakes place the water is shut oli' from the tank C and the plumberorother person can make repairs connected with the tank C.

From the foregoing itl will be seen that by the arrangement describedthe screw Q not .only serves as a limitin stop for the stem J and thevalve disk H ut it also serves to completely close or seat the valvedisk H on the seat D and to hold the same lockedv in this closedposition until the desired repairs on the tank or connected parts havebeen made. When this has been done the screw Q is again screwed outwardto allow the valve disk H and its stem J -to slide freely in the valvebody A for opening and closing the seat D. y 'i The valve shown anddescribed is very simple and` durable in construction and is composed ofcomparatively lfew parts not liable easily to gety out of order, and.which can be readily repaired whenever necessary. It will also benoticed that by the use of the screw Q the valve disk H can be movedinto closed position and completelyvshut oil the supply of water. l y

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

A valve, comprising a valve body provided with a seat and with .atubular bearing, the outer end of the said tubular bearing having a slotat the under side, a valve disk having a stem mounted to slide in thesaid bearing, the disk being adapted to open and close'the said seat,a'lever extending through the said bearing slot and provided with aclosed slot, a transverse pivot pin removably held on the said bearinand having its axis extending within the ore of the bearing intermediatethe axis of the bearing and the inner surface of the bearing, the

pivot pin also extending through the said closed slot, and a pin on thesaid valve stem and engaging in the said closed slot.

2. A valve, comprising a valve body hav-y .ably held 0n the saidbearing,

.inner surface of the bearing,
